Question #4

Does my iPhone or Android device support eSIM?

Answer #4

Most modern Android flagship and mid-range devices (2019 and newer) support eSIM. A few things to check:

1. Your device must be eSIM-capable (hardware support)
2. Your device must be unlocked or purchased directly from the carrier (carrier-locked phones may block third-party eSIMs)
3. Your iPhone device
4. Your Android OS should be version 10 or higher for the best experience. This will depend on the Android model and version. Not all Android models are the same.

Not sure if your device is compatible? Visit the Compatibility page at the top of the portal to check your specific model.

Question #5

Do I need to remove my existing SIM to use a LandmarX eSIM?

Answer #5

No. eSIMs work alongside your existing physical SIM. You can keep your home carrier SIM active for calls and texts while using your LandmarX eSIM for data while traveling. Most Android devices support dual SIM (physical + eSIM) natively.
